Who can build an ADU - Accessory Dwelling Unit on their property?

Accessory Dwelling Units (ADU's) are a great way to enhance the value of your home.  They can provide independent housing for family members and caregivers or can be rented to supplement monthly income.  There is also the option for homeowners to downsize and live in the ADU while renting out the main house.  

ADU's can be located in a variety of places on the property.  Typically, they are a garage conversion, a re-vamping of existing space within the home, or a separate structure on the property which has been converted or built specifically for use as an ADU.

The size allowable for the ADU is determined by a number of factors including the lot size, the current lot coverage and the square footage of existing structures. The State of California sets limits, however, local zoning regulations apply that ultimately determine the maximum size ADU for each property.

The following apply to all ADU's :

1. Lot must be zoned for single-family or multifamily use and contain an existing, single-family dwelling.
   
2. ADU must have independent exterior access from the existing residence
3. ADU must have a minimum size equivalent to that of an efficiency dwelling unit (150 square feet)
4. ADU is limited to a maximum size of 50% of the existing structure - but cannot exceed 1200 square feet
5. ADU cannot be sold separately from the main home 
6. Only one ADU is permitted on a property
7. Owner occupancy is not required by the state; however, local governments can require an applicant to be an owner occupant.
8. If the property is within half a mile of public transportation, additional parking for the ADU will not be required.
